Start from the fueling positions on the apron plan, then trace each hydrant pit or fueling station back through the piping, valves, and emergency fuel shutoff system, and check that every discipline shows the same arrangement. AI can flag conflicts; the fuel system engineer, the airport, and the authority having jurisdiction decide compliance.
What does NFPA 407 cover?
NFPA 407 is the Standard for Aircraft Fuel Servicing. NFPA’s page states that it outlines safety provisions for procedures, equipment, and installations to protect people, aircraft, and other property during ground fuel servicing of aircraft using liquid petroleum fuels.
NFPA’s official NFPA 407 page identifies the 2027 edition as current when checked on October 9, 2026. Confirm the edition, local amendments, and project scope that actually govern the work. The publisher’s newest edition does not establish local adoption.
The terminal side of the apron, including fueling ramp drainage, is covered in the NFPA 415 terminal guide, and the fuel storage tanks usually follow the NFPA 30 guide. Aviation agencies and the airport also publish their own fueling requirements, so record which documents govern the project before comparing.
Gather the apron, the piping, and the shutoff system
Collect the apron and gate layout with aircraft parking positions, the hydrant pit and valve details, the fuel piping plans and profiles, the emergency fuel shutoff plans and station locations, the electrical and bonding drawings, the fuel farm or storage drawings, the apron drainage plans, and the fuel system specifications.
Fueling systems are often designed by a specialist consultant on a separate sheet series. Upload those sheets with the airfield and terminal drawings so each pit and shutoff can be compared with the gates they serve.
Follow the fuel from the farm to each aircraft position
| Review question | Sources to compare | Decision to record |
|---|---|---|
| Fueling positions | Apron layout, gate plans, hydrant plans | Confirm each aircraft position has the same hydrant pits on the apron and fuel system drawings. |
| Piping route | Fuel piping plans, profiles, civil plans | Trace the piping between the fuel farm and the apron and find routes that differ between sheets. |
| Valves and pits | Pit details, valve schedules, specifications | Match pit and valve types between the details, schedules, and specifications. |
| Emergency fuel shutoff | Shutoff plans, electrical drawings, apron layout | Check that each shutoff station appears in the same place on every discipline’s drawings. |
| Bonding and electrical | Electrical plans, fueling details, specifications | Find bonding or electrical provisions at fueling positions that one source shows and another omits. |
| Drainage | Apron drainage plans, civil plans, fuel plans | Ask the designer to confirm how spills at the fueling positions are drained and that sources agree. |
Aircraft maintenance in hangars is covered in the NFPA 410 guide and hangar construction in the NFPA 409 guide. These questions come up on airport projects; use the civil site checklist for the apron and drainage.
Example: a gate added without a hydrant pit
Hypothetical example. A terminal expansion adds a new aircraft position at the end of a concourse. The apron layout and the gate plans show the new position, while the fuel hydrant plans and the emergency fuel shutoff plan still end at the previous gate.
The apron layout shows a new aircraft position at the end of the concourse, but the hydrant plans and the emergency fuel shutoff plan end at the previous gate. Please confirm whether the new position is fueled by hydrant and coordinate the piping, pits, and shutoff stations.
The fuel system consultant confirms the fueling method and updates the drawings. Compliance is decided by the engineer, the airport, and the authority having jurisdiction.
Review an aircraft fueling package with Groundbook
Upload the current project PDFs and relevant specifications to Groundbook. Identify the governing issues and add the applicable NFPA 407 reference from a copy you are licensed to use, where the license permits uploading it. State the edition, amendments, review area, and known exclusions in your instructions.
Compare the apron and gate layout, hydrant pit and valve details, fuel piping plans and profiles, emergency fuel shutoff plans, electrical and bonding drawings, fuel farm drawings, apron drainage plans, and specifications. Flag fueling positions, piping routes, pits, valves, shutoff stations, and drainage that differ between sources. Use the supplied NFPA 407 edition where applicable and cite both sources.
Groundbook links each potential finding to the sheets involved and the reference you uploaded.
Document review does not size the fuel system, check fueling procedures, or approve the installation. Those decisions remain with the design team, the airport, and the authority having jurisdiction.
